I just installed Ubuntu 16.04 on a new Dell XPS laptop, and everything is working great out of the box except that Ubuntu will not reboot or power down. Attempting to reboot from the menu in the upper right corner of the GUI does nothing (dialog closes with no failure message and the system does not shut down). From the terminal I get:
$ sudo reboot Failed to start reboot.target: Transaction is destructive. See system logs and 'systemctl status reboot.target' for details. $ sudo systemctl status reboot.target ● reboot.target - Reboot Loaded: loaded (/lib/systemd/system/reboot.target; disabled; vendor preset: disabled) Active: inactive (dead) Docs: man:systemd.special(7)
with similar results for sudo shutdown. Is this a bug or is there a fix? Thanks!
